Tell me about the new DLC Shen \ 's Last Gift (XCOM 2)

People, tell me about the new DLC Shen's Last Gift. After the release of the DLC in the continuation of the game after loading the save, the DLC activation window appeared. Actually, I activated it. And how to start this task? It did not appear where, although it allows you to explore robots. Or will it appear during the game? Since I have already completed a couple of missions after activating the DLC, nothing has appeared, except for a robot in research. I hope you don't need to start a new game?
